To all lwhom [t may concern:

Be it known that l. VVILUELM R. HT- 'rlxonm a citizen of the United States. residing at Beverly. in the county of Burlington and State of New Jersey. have invented certain new and useful Improvements in GaAs-Producers, of which the followingr is a specification, reference being had therein to the accompanying drawing, fornnngr a part thereof.

This invention relates to gas-producers and has for its objects. generally, large storage capacity for fuel; a uniform distribution of draft at. the place of combustion; the longest possible contact of the heated gases with the stored fuel; the retention of dust in the fuelehamber until consumed. effective contact of the gases tlowing from the point of combustion with water-cooled surfaces of vapor-generating and air-preheating means and especiall)Y a highly ei"- leetive contact otE the freshly heated gases with the water-cooled top of the fuel-chamber and the effective heat insulation of the fuel-chantier b v such vapoiglenerating and air-preheatingr means: remllation ot' the quality of the gas supplied by the producer in relation to the rate of consumption thereof so as to supplyT a. rich ,gras when the demand is at a` maximum and a lean gras when the demand is at a minimum. thereby greatly assisting the regulation of an engine to which gas is supplied; and other objects which will appear from the following;y description.

l will now describe the apparatus embodying my invention shown in the ac o1npanying drawings and will thereafter point` outV my invention in claims.

Figure 1 is a vertical longitudinal section of the gas-producer. Fig. Q is a horizontal sectionof the same taken on a plane indi cated by the line Fig. 1. Fig. 3 is a horizontal section of the same taken on the plane, indicated b v the linel il il. Fig. 1. Fig. L1 is a side elevation of the gas-producer and gasscrnbber and intermediate connection. the latter being shown in vertical central section. Fig. 5 is a transverse vertical seetional, detail of the regulator. Fig. is a vertical section of the same. Fig. 7 is a longitudinal vertical `section of a modified l'orrn of regulator.

The ,eas-prmucer shown is of the lowpressure or suction`- type and in its` northe gas supplied at the point of consump- .gated so as to contain a considerable charge of fuel and has a refractory lining 8 inelosed within a metallic shell 9, and the fuel is supported upon a revolving grate 10 having a surrounding annular ash-supportingr flange 11. the whole beingr carried on ball bearings 12 on a hollow standard 13 in the ash-pit 14. The fuel is supplied from a charging' hopper 15. having a tightly closable cover 1G of usual construction and havingr a movable valve or bottom 17 which closes the charging opening of the fuelohamber and seats downward and toward the interior of the fuel-chamber so that the `weight of the fuel in the hopper and the outer atmospheric pressure both 'tend to hold it tight and prevent air leakage into the Agasprodueer. This movable valve 17 is operated bv a pivot'ed lever 18 extendingout` of the hopper for convenient operation and connected at its inner end by a rod 19 with the movable bottom 17, and the movable bottom is guided hv wings Q0.

The casing of the gas-producer includes an upper vaporizing chamber 21 and a lower vaporizing chamber 22. these two chambers covering and surrounding the fuel-chamber. These vaporizing chambers are also air-preheating chambers. the upper chamber drawingr in air from the atmosphere through a curved air-inlet pipe 23 and deliveringr this air commingled with steam to the lower vaporizing chamber through a conduit 24. This upper vaporizing chamber is supplied with water as shown so as to cover all of the metallic surfaces exposed to the he'ated gases from the fuel-chamber. The conduit` 24. as aforesaid. conveys to the lower vaporizing chamber the air which has entered the upper vaporizing chamber and has been heated therein and also conveys to the lower vapormal operation the draft is maintained and i izing chamber, commingled with the air. the

steam which has been generated in the upper waporizingchamber. The lower vaporizing chamber 22 if. supplied with water up to about the level shown in Fig. 1 and by reason ot the fact that it forms a water jacket about the place of combustion is very highly etlectire as a v:iper-producer or steanrgenerator. lt. is also traversed by vertical llues which conduct downward the heated eases from the fuel-chamber7 these flues beingr shown as cast in the metallic shell surrounding the combustion chamber and spaced at such distances apart, as shown in Fig. that they do not materially shield the metallic shell from Contact with the water in the vaporizing chamber. Thus the vaporizing ehan'iber is an ettective steam generator traversed by fines conveying heated gases and jacketing the fuel chamber wherein the gas-producing combustion is maintained.

conduit 26 leads from the lower vaporA izing chamber 22 to the hollow standard 13 in the ash-pit and this conduit has interposed therein the regulator for varying the quality of the gas supplied by the producer, and also has connected thereto a hand blower Q7 for use in initiating" the operation of the apparatus. The regulator comprises two valves, an air-inlet valve 30 which, when opened, permits the outer air to enter the conduit QG, and a passageway valve 3l which is interposed in the conduit Bti. These two valves directly enter a box which is part oi" the conduit., and they are operated by a pivoted lever 33 secured upon a sha lt lil upon which is also secured an outer arm 33 which is connected by a rod 36 with a regu` latino dial'ihragm 3i. The diaphragm 25T is held in a easing $153 and is exposed on its lower face to the pressure ot the atinosl'ihere and is subjected on its upper face to the in ternal pressure of the apparatus at a snitable polnt where the pressure will vary with variations in the delivery pressure of the gas. The point selected is the upper part of the gas-scrubber 40 and from this point a small conduit or pipe 39 is led to the upper part of the diaphragm-casinY 38, and the pressure ati this point; will depend upon the delivery pressure of the gas, this delivery ircssure varying willi the rate at which tlugas is withdrawn from the apparatus or the rate of consumption ot the gras. This diaphragm will therefore respond to variations in the consumption of the gas so that when the engine or other gas-utilizing or withdrawingr device is using large quad tities of gas and there-lore causing a` low pressure in the delivered gas. the diaphragm 5V." will he raised, as shown in Fi". ti. and the air-inlet valve il() will be tightly closed and the passageway-valve 'll fully opened. Under these conditions the maximum quantity of steam will he delivered at the point under the protectingt cowl t3 and of coinluzstion and the full gasenrichinfr capacity of the apparatus will be developedi When, however, the consumption of gas diminishes and in consequence thereof the pressure of the delivered gas rises, the diaphragm 3i' will he moved downward, openingr the air-inlet valve 30 and admittinzgr outer air directly to the box and closing the passageway-ralve 3l and ilnkeding the passage ot' the eommingled preheated air and steam ici-oir` the raporizing chambers through the conduit 2Q thus increasing the proportion of air and diminishing the proportion of steam in the lgaseous material supplied at the point of combustion and to some extent lowering the te iperature of such gaseous material but; principally diminishing the amount of moisture therein and thereby dinnnlshingr the number of heat Yunits required at` a point of comlaistion.y and causing,r the production of a lean gas or a gas containing a small proportion of hydrogen and a large proportion of nitrogen, and also tending to maintain a constant teniperatnre o'l combustion. Thus the governing of an engine will be greatly assisted and the ellieieney of gas prodlution\and consumption increased.

The air-inlet` valve 30 is carried upon a rod 4l which passes through a .sleeve ft2 and carries a lift-cam t3 at its upper end cooperatiner with the upper end ot thesleere l2 to draw the rod Lt1 up into the sleeve and more into and hold in closed positions linth the air-inlet valve fl() and the passageovar valve ill. This lifting cani is designed to lie used in the initial operation of the appa.- ratus when the combustion ol' the V`uel is started by a forced draft I'roin the blower Q7. it damper lll at the connection nl' the blower with the conduit Bti is ordinarily closeth hut during this initial operation this damper is operiert and the valvesY 20 and 'll are closed by the lit't-ea|n. as above der-1rri|iedtand ai:- is l'orred through the appalltlls liv the operation of (he Idou'er.

('ommingled air and steam in vanring proportions dependingr upon the operation of the regulator, or air alone during the initial operation, pass from the ronduit. 2G up through the. hollojwr standard lil and thenre up through the apertures of the f jrate l0 into and through the mass of solid t'uel. The combustion taires piave in thel lower pari ot' the fuelchinnher` hut the heated gases are compelled-to pass upward through snhslantially the Whole charge ot' fuel in the l`uel` chamber. thus impartingy a portion ot their heat to the 'Fuel above the point of combos! tion and.preheating the fuel. The heated gases emerge from the fuel in the enlarged upper portion of the fuelehamber wherein is provided a dethetor-wall 4G, which rxtends up into close proximity to the waterlflO cooled top 47 of the fuel-Chamber no as to leave a realrieled annular oriliee llettween the top of the luel-rhaiolier and the top ot the delleetor-Wall, this;4 annular oriire heini; the gas-outlet from the fuel-rhatnher. Through this gaaavutletz extending entirely around the upper part of the Chamber, the heated gases ewape into an outer annular rhani her llS. This ehanlher 4H :aerrra as an ex'- pansion ehainher for the gases. Sint-e the restrieted outlet opens into the top ot the` expansion ehatnher 4S. the direction ot the' gases is reversed with the result that eddiefsl are Set up whirh Gauraithe solid particles to he precipitated against the hides. of the elianiher lil troni where they ufraritate and are deposited on the hottoni of the rhainher. The enlarged upper part ot' the fuel Cham-- her has an inclined lm'ver eut-fare Ll!) sloping inward toward the renter of the ehainher. and tln` (loller-tor-wall and restricted outlet eauee the, dellertion and deposition of particles ot' dust; which gravitate toward the point` of eoinhnation, the thuhl heini;r suhieoted to an abrupt` turn Whieh rannot he followed hv the larger LSolid partieles. The defleetonwall and reatrieted outlet also a5- Sure the intimate eontac't of the heated gases with the \\'atereooled top oi the fuelehainher. They also assure a uniformity of draft all around the vfuelAehaniher. preventing the formation of loc-al hurneddutt posisages through the fuel Whit'h reault where the rasee eseape at one eide of the fuel chainher or esc-ape troni the fuel-ehaniher at one point only.

The annular eltaniher tf-3 into whieh the gases enter after pasfiing through the restricted annular outlet over the top o'f the delleetor-wall, is surrounded h v a waterdefr formed hy the lower part of the upper Ya.- porizing' ehaniher 2i and thus ite outer sur fares are water-rooled. From this annular ehaniher 4S `the gases tion downward through the linea `which. as ahove deserilied, are formed in the easing surround ing; the fuelha1nher and which are Shown as eulistantiallyr and may he entirely Snrrounded hy the water in the lower raporixing chamber QQ, From the linea4 Q5 the gaeu paas into a lower annular ehainher .7U and from this lower annular ehaniher 50 ther are rornlurted through the ':oing (il ol a double seated valve whirh may he closed on iteI lower seat so that the galera n'ill pass upward through the conduit 535 to a ehimney or other point of diseharge, as is desirable on starting the operation of the gas-producer, or may be closed on its upper seat, as showin causing the gaaes to pass downward through the flaring conduit against the upper anrlae of ivater in tht, drain-tank 54, and from the drain-tank 54 into ehe gasheruhher 40. From the gaasernbber thegasea may be led directly to the engirte-eylinder or to the gas-pu1np of the engine or to aniY ,Quitahle apparatus wherein the is utilized and whereby ity is drawn :zwar troni the gasprodueer so as to maintain the desired low pressure therein.

The gas-scrubber thatY he of any usual or `mital'lle construction and is therefore -Qhown only exteriorly. The draiirtanl 5l receives the Water orertlowing lronl the lower part ot the gas-scrubber and also is elleetive in separating dust :from the gases hy reason of the im nlsion of the gases against the surface o the Water in the draIrank effected by means ofthe flaring conduit 55.

For eonvenient eleaning of the lower annular-eliainlwr of the gas-produeer, several movable hand-holes 5G are provided at the outer wall of such annular chamber, and for poking the fuel and cleaning the upper enlarged portion of the fuel-chamber Feveral openinga` are provided in the top ot' the gas-producer and are closed hy tapering plugs 57. The top of the upper vaporizing chamber is secured by boltsS Yto its side eylindriaal portion and may be readily removed. and` accese may then be had to the `Vertical fines 25 by removal of. the handhole plates 59 located in the top easing 47 of the fuel-chamber direetlir over the upper annular chamber 48 and in substantialv alineinent with the vertical fines 25.

Suitable means are provided for supplying vater to the vaporizing Chambers and maintaining the fluid levels therein and also supplying water to the gas-scrubber. The Water Supply pipe (S5 leads directly to the gas-serulfiher and ha 4 a hraneh pipe 6G ex* tendingr downward and having a valve 6T therein with its nipple immediately over the upper end oi the supplyv and drain piping of the vaporizing ehalnhers. This Supply and drain pipinlggl includes a pipe (i8 connected to the upper raporizing chamber and also eonneeted to a pipe (if) at such a point that: it, will overflow into this pipe 6l) when the normal level in the upper vaporizing chainher ie exceeded. The pipe (El ia Connected to the lower raporiaing chamber and is also connected to a drain pipe at sueha point that it will overflow into auch drain pipe when the normal water level in the lower raporizing eliainher exceeded. f
